26 ;;; Commentary:
27
28 ;; This package provides the tools meant to help editing PO files,
29 ;; as documented in the GNU gettext user's manual. See this manual
30 ;; for user documentation, which is not repeated here.
31
32 ;; To install, merely put this file somewhere GNU Emacs will find it,
33 ;; then add the following lines to your .emacs file:
34 ;;
35 ;; (autoload 'po-mode "po-mode"
36 ;; "Major mode for translators to edit PO files" t)
37 ;; (setq auto-mode-alist (cons '("\\.po\\'\\|\\.po\\." . po-mode)
38 ;; auto-mode-alist))
39 ;;
40 ;; To use the right coding system automatically under Emacs 20 or newer,
41 ;; also add:
42 ;;
43 ;; (autoload 'po-find-file-coding-system "po-compat")
44 ;; (modify-coding-system-alist 'file "\\.po\\'\\|\\.po\\."
45 ;; 'po-find-file-coding-system)
46 ;;
47 ;; You may also adjust some variables, below, by defining them in your
48 ;; '.emacs' file, either directly or through command 'M-x customize'.

50 ;; TODO:
51 ;; Plural form editing:
52 ;; - When in edit mode, currently it highlights (in green) the msgid;
53 ;; it should also highlight the msgid_plural string, I would say, since
54 ;; the translator has to look at both.
55 ;; - After the translator finished the translation of msgstr[0], it would
56 ;; be nice if the cursor would automatically move to the beginning of the
57 ;; msgstr[1] line, so that the translator just needs to press RET to edit
58 ;; that.
59 ;; - If msgstr[1] is empty but msgstr[0] is not, it would be ergonomic if the
60 ;; contents of msgstr[0] would be copied. (Not sure if this should happen
61 ;; at the end of the editing msgstr[0] or at the beginning of the editing
62 ;; of msgstr[1].) Reason: These two strings are usually very similar.
